BELL. 1

srnerrrearron forming part of Letters Patent No. 654,324, dated. July24, 1906.

Application filed February 26,1900. Serial No. 6,488. (No man.)

To all whom it may concern:

Be it known that I, HERBERT S. PULL'MAN, a citizen of the United States,and a resident of Meriden, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements in Bells,of which thefollowing is a specification.

My invention relates to the general class of alarm or call bells; and myobject is to provide a striking mechanism for such bells that willproduce the effect of an electric bell in the rapidly-repeated strokesof the hammer when the bell is operated. Referring to the drawings,where one form of embodying the invention in a bell is shown, formingpart hereof, Figure 1 is a top or plan view of the base of the bell andthe operating mechanism, the gong being removed. Fig. 2 is a view inside elevation of the bell, the gong being out in central section. Fig.3 is a detail view, on enlarged scale, showing the ratchet-drive incentral section.

In the accompanying drawings the letter a denotes the base of the bell,which may be of any convenient form with ordinary means to support thestructure in proper position for use.

On the base 0. is secured a post I), the outer end of which bears a gongo, secured in any convenient manner, the post being hollow or tubular toreceive the plunger 01, which has a sliding movement therein, the arm don the plunger projecting through a slot in the side wall of the postZ).

To a fixed part of the frame of the structure and preferably on the sideof the post I) a bell-crank lever e is pivoted, with its outer end 6'underlying the arm 01 on the plunger and its opposite end connected byalink f with one end of the striker-lever g. This strikerlever gispivoted to the base of the bell, as at 77., and has on its outer end asegmental gear 9, which is in mesh with a pinion t'. This pinion issecured to the hub 7c of the ratchetwheel 70, which is pivotallysupported on the post Z on the base a. On the same hub 76 anescapement-wheel m is loosely mounted, so as to turn freely in onedirection while held from any sliding movement along the hub, and bymeans of the spring-pawl n pivoted to the side of this escapement-wheelm the ratchet-wheel 7c is connected to the wheel m,

so as to turn with it in the reverse direction. A verge o, withpallet-teeth in suitable engagement with the escapement wheel, ismounted on arock-shaft to which the arm 19" of the bell striker orhammer p is secured. When the escapement-wheel is forcibly rojtated inone direction, the verge will be caused to vibrate rapidly and the gongto sound. The striker-lever is held in the proper posi tion of rest bymeans of a spring 7', one end of which is anchored to the base and theother attached to the lower end of the bellcrank lever, as shown in Fig.1 of the drawings.

To operate the bell, pressure is applied to the cap of the plunger d, sothat the arm d thrusts against the end e of the bell-crank le-' ver,tilts the latter, and through the link f 6 no reverse movement, theratchet-wheel turning freely under the pawl in this resetting of themechanism.

What I claim as my invention, and desire to secure by Letters Patent, is

l. A bell-base, bell-striking mechanism supported by the base andincluding a pinion, a hollow post supported on the base, a strikerleverpivoted to the base with one end having a segmental gear meshing withsaid pinion, a bell-crank lever pivoted on the post, a link connectingthe bell-crank lever with the striker-lever, a plunger supported by thepost and having an arm overlying an arm on the bell-crank lever and agong secured to the 0st. p 2. A bell-base, bell-striking mechanismsupported by the base and including a single pinion, a hollow postsupported on the base, a U-shaped lever with its branches lying onopposite sides of said post, one branch bearing a segmental gear meshingwith said pinion, and the other branch forming a connection for a link,a bell-crank lever pivoted on the post, a link connecting the bell-cranklever with the U-shaped lever, a plunger sup and an escapement-wheel, afixed stud, a

ratchet-wheel mounted to turn on the stud and having an elongatedhub,the escapelnentto wheel mounted to turn on the hub, a pawlconnecting the ratchet-Wheel and the escape ment-Wheel, a pinion securedto the hub of the ratchet-Wheel, a striker-lever in engagement with saidpinion, and means for operating the striker-lever.
